Objective

According to NASCET- and ECST-study carotid endarterectomy (CEA) reduces the risk of stroke in patients with symptomatic severe carotid stenosis. However there is still a risk of perioperative complications of about 5%. We tried to identify defined risk groups for perioperative ischemic incidents in our patients whose multilocular vascular pathology necessitated a neurosurgical intervention to avoid perioperative stroke.

Methods

Two hundred and eighteen CEAs were performed in 208 patients either uni - or bilaterally. In order to find a potential risk profile, patients were devided into groups with and without perioperative ischemic incident. To ascertain whether incident of risk factors were accidental or based on certain risk criteria, statistical analysis was performed with the Chiquadrat Test and the Jonckheere -Terpstra Test.

Conclusions

The existence of predictive factors for the appearance of perioperative ischemic incidents in candidates for CEA will help to identify patients with a pronounced risk of perioperative complications; these should be operated on using meticulous policy such as microsurgical technique, intraoperative monitoring and neuroprotective measures.
